Use both glue and screw first. With a countersunk screw that doesn't fit properly in the hole, a screw won't be able to hold it flush. Don't just rely on duct tape to keep them on the wall. Together these two methods will work well. Second, they may not fit all of the controllers listed in the title, even if they are wall mounted. They are too wide and flat for my Xbox 360 controller, which falls out between the grips due to the rounded center section. However, it goes well with the Steam controller and my headset. I added some foam padding for my controller and it holds up better, although it detracts from the foldability they promoted. I'll keep them but if I had to replace them it wouldn't be with this product.
